The word MATH is repeatedly written producing the pattern MATHMATHMATH... If the pattern is continued, what letter will occur in the 1000th position?
See this pattern:
M - 1, 5, 9, 13, 17...
A - 2, 6, 10, 14, 18...
T: 3, 7, 11, 15, 19...
H: 4, 8, 12, 16, 20...
Do you think you can use this information to extrapolate the 1000th position?
Edit: Think about 997, 998, 999, 1000. Where will these fall?
MATH has a "period of 4"
Therefore: 1000 mod 4 ==0, which means the last letter of MATH, or H
